RESUMO

With Zang-Fu organs, meridians, Qi and blood, and body fluid as the physiological and pathological basis, traditional Chinese medicine(TCM) theory is guided by the holistic concept and characterized by syndrome differentiation. It has made significant contributions to human health maintenance and disease prevention. Modern TCM preparation is developed on the basis of inheriting and developing TCM preparations using modern science and technology under the guidance of TCM theory. At present, the incidence and mortality of common tumors are increasing. TCM has rich clinical experience in the treatment of tumors. However, in the current stage, some TCM preparations have a tendency to deviate from the guidance of TCM theory. With the modernization of TCM, it is worth considering how TCM theory guides modern TCM preparations. Taking tumor treatment as an example, this paper introduced the development of TCM nano-preparation under the influence of modern nanotechnology, summarized the research on the development of modern TCM nano-preparation from the aspects of TCM holistic concept, TCM treatment principles, and TCM theory application, and discussed the application prospect of TCM nano-preparation in overall therapy, drug pairing, carrier selection, and targeted substance selection under the guidance of TCM theory. This paper provides new references for further developing the combination of tradition and modernization of TCM nano-preparation.

RESUMO

BACKGROUND: Myopia are common health problems that people experience in daily life. Pediatric myopia has become a major international public health concern that has a negative impact on physical, mental health of patients, and quality of life. Currently, there is no cure available. Press needle as an adjuvant therapy is currently undergoing clinical trials in different medical centers. However, no relevant systematic review or meta-analysis has been designed to evaluate the effects of press needle patching on early myopia. There is also a lack of systematic evaluation and analysis of acupoints and thumbtack needle. METHODS: We will electronically search Medline, Embase, PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database, and Wan-Fang Database from their inception to October 2021. In addition, we will manually retrieve other resources including the reference lists of identified publications, conference articles, and gray literature. The clinical randomized controlled trials or quasi-randomized controlled trials related to press needle for the treatment of early myopia will be included in the study. The language is limited to Chinese and English. Research selection, data extraction, and research quality assessment will be independently completed by 2 researchers. Data were synthesized by using afixed effect model or random effect model depend on the heterogeneity test. The total effective rate was the primary outcomes. RevMan V.5.3 statistical software will be used for meta-analysis. If it is not appropriate for a meta-analysis, then a descriptive analysis will be conducted. Data synthesis will use the risk ratio and the standardized or weighted average difference of continuous data to represent the results. RESULTS: This study will analyze the clinical effective rate, pesudomyopia outcomes, quality of life, improvement of clinical symptoms of pesudomyopia, and validity of thumbtack needle for patients with pesudomyopia. CONCLUSION: This systematic review will provide evidence to judge whether thumbtack needle is an effective intervention for patients with early myopia.

RESUMO

In recent years,the development and application of classical famous prescriptions have attracted much attention. However,the differences between ancient and modern conditions lead to difficulties in carrying out practical work. In this paper,with Houpu Wenzhong Decoction as an example,the key technologies of boiling granularity,water addition,boiling time and sample pretreatment methods were investigated on the basis of sufficient literature research. The experimental results showed that there was no significant difference in the concentration of index components between those with different granularity( 2 mm and 3-5 mm) and different decocting time( 30 min and 60 min),but the extraction rate of index components was relatively high when the granularity of powder was 2 mm and decocting time was 30 min. With the increase of water content,the concentration of index components and the extraction rate were increased in varying degrees. A certain proportion of methanol aqueous solution was used as the resolvent before content determination of the reference sample of Houpu Wenzhong Decoction,which could take into account both the spectral information of water-soluble components and fat-soluble components in the prescription,and help to display the overall information of the prescription' s chemical components more comprehensively. At the same time,the boiling and dispersing classical prescriptions in the Catalogue of Ancient Classical Prescriptions( the first batch) were collected and summarized in this study; the key influencing factors of decocting process were analyzed from different angles,and preliminary research suggestions were put forward,so as to provide a certain direction and reference for the establishment of quality standard of Houpu Wenzhong Decoction,as well as for the development,research and clinical application of boiling and dispersing classical prescriptions.

RESUMO

Methicillin-resistant Staphylococcus aureus (MRSA) infections are a significant global health challenge due to the emergence of strains exhibiting resistance to nearly all classes of antibiotics. This necessitates the rapid development of novel antimicrobials to circumvent this critical problem. Screening of compounds based on phenotypes is one of the major strategies for finding new antibiotics at present. Hence, we here performed a phenotypic screening against MRSA and identified NPS-2143 exhibiting activity against MRSA with an MIC value of 16 µg ml-1. In order to discover more potent anti-MRSA agents, a series of derivatives of NPS-2143 were designed and synthesized. The most promising compounds 48 and 49 exhibited favorable antimicrobial activity with an MIC value of 2 µg ml-1.

RESUMO

<p><b>OBJECTIVE</b>To investigate effect of Compound Danshen Dripping Pill (CDDP) on the inflammatory response of the myocardium of acute myocardial infarction (AMI) rabbits, to observe the therapeutic effect of CDDP combined intravenous transplantation of human umbilical cord blood mononuclear cells (HUCBMCs) on inflammatory response, pro-inflammatory cytokine tumor necrosis factor alpha (TNF-alpha) , and heart function in the myocardium of AMI rabbits, and to explore the possible protective mechanisms of the combined therapy.</p><p><b>METHODS</b>The AMI model was successfully established by ligation of the left anterior coronary artery (LAD) in 40 healthy rabbits.Then they were randomly divided into four groups, i.e., the control group, the CDDP group, the transplantation group, and the combined group, 10 in each group. Rabbits in the control group received intravenous injection of 0.5 mL normal saline via ear vein within 24 h after AMI and then intragastric infusion of normal saline at 5 mL per day. Rabbits in the CDDP group received intravenous injection of 0.5 mL normal saline via ear vein within 24 h after AMI and then intragastric infusion of solution obtained by solving 270 mg CDDP in 5 mL normal saline per day. Rabbits in the transplantation group received intravenous injection of 0.5 mL normal saline labeled with green fluorescent protein (GFP) containing 3 x 10(7) of HUCBMCs via ear vein within 24 h after AMI and then intragastric infusion of normal saline at 5 mL per day. Rabbits in the combined group received intravenous injection of 0.5 mL normal saline labeled with GFP containing 3 x 10(7) of HUCBMCs via ear vein within 24 h after AMI and then intragastric infusion of solution obtained by solving 270 mg CDDP in 5 mL normal saline per day. At week 1 and 4 after treatment, cardiac function indices such as left ventricular fractional shorting (LVFS) and left ventricular ejection fraction (LVEF) were performed by echocardiography; the number of transplanted cells in the myocardium was found by GFP positive cells counted with fluorescence microscopy.The white blood cells in the myocardium stained with HE were determined by light microscope. The expressions of TNF-alpha protein in the myocardium were detected by immunohistochemical assay.</p><p><b>RESULTS</b>(1) Compared with the control group at week 1 and 4 after treatment, the LVEF and LVFS were significantly improved in the CDDP, transplantation, and combined groups (P < 0.05). The cardiac function was significantly improved in the combined group than in the CDDP group and the transplantation group (P < 0.05). But there was no statistical difference in the latter two groups. (2) Compared with the control group, the number of white blood cells and the expression of TNF-alpha protein decreased significantly in the CDDP, transplantation, and combined groups at week 1 and 4 respectively after treatment. The number of white blood cells and expressions of TNF-alpha protein were significantly lower in the combined group than in the CDDP group and the transplantation group (P <0.05). But there was no statistical difference in the latter two groups. (3) GFP-positive cells were found to be distributed in the peri-myocardial infarction area in the transplantation group and the combined group at week 1 and 4 after transplantation. Besides, the number of the GFP positive cells was much more in the combined group than in the transplantation group (P < 0.05).</p><p><b>CONCLUSIONS</b>The findings indicated that the combination of CDDP with intravenous transplantation of HUCBMCs in the treatment of AMI rabbits could elevate the survival rate of transplanted cells, and further improve the heart function. The possible mechanisms might be related to attenuating local inflammation of myocardium, and inhibiting enhanced expressions of pro-inflammatory cytokine TNF-alpha protein.</p>

RESUMO

<p><b>OBJECTIVE</b>To explore the effectiveness of the traditional Chinese herbal medicine Lingzhi (Ganoderma lucidum) preparation in treating simian acquired immune deficiency syndrome (SAIDS).</p><p><b>METHODS</b>Five female adult Chinese rhesus monkeys were inoculated rectally with SIVmac239, and were all diagnosed as SAIDS by laboratory and clinical examinations 17 months later. Of these 5 monkeys, 3 (#393, #374, and #381; treatment group) were orally administered with Ganoderma lucidum (2 spores powder capsules plus 2 spores oil capsules on a daily basis), and the remaining other two monkeys (#348 and #361) served as control and did not receive treatment.</p><p><b>RESULTS</b>Animal #393 (treatment group), #361 (control group) and #348 (control group) died of SAIDS (opportunity infection) 3.5 months, 6 months, and 11 months later, respectively. Two animals (#374 and #381) survived. The necropsy revealed depletion and/or exhaustion of their lymphoid tissue. In the monkey #374, the peripheral CD4(+) T lymphocyte increased by 30% in the 6(th) month compared with the baseline level and then fluctuated. The plasma viral load gradually fell and reached about 1 log(10) in the treatment group, but remained stable in the control group. As shown by pathological examinations, the lymph node and spleen of monkeys #374 (treatment group) and #381 (treatment group) showed rehabilitation and reconstruction in the lymphatic tissue, thymus, nerve tissue of gyrus hippocampi, pituitary gland, pineal body, thyroid gland, adrenal gland, and ovary.
